Segmenting a French Meeting Corpus into Elementary Discourse Units
No full textInternational audienceDespite growing interest in discourse-related tasks, the limited quantity and diversity of discourse-annotated data remain a major issue. Existing resources are largely based on written corpora, while spoken conversational genres are underrepresented. Although discourse segmentation into elementary discourse units (EDUs) is considered to be nearly solved for canonical written texts, conversational spontaneous speech transcripts present different challenges. In this paper, we introduce a large French corpus of segmented meeting dialogues, including 20 hours of manually transcribed and discourse-annotated conversations, and 80 hours of automatically transcribed and segmented data. We describe our annotation campaign, discuss inter-annotator agreement and segmentation guidelines, and present results from fine-tuning a model for EDU segmentation on this resource.</div
The influence of fine motor skills and executive functions on automatized handwriting
No full textInternational audienceWe aimed to explore the understudied area of typical adult handwriting performance, focusing on the potential predictive roles of fine motor skills and executive functions. While the initial stages of handwriting acquisition are assumed to rely upon executive functions and fine motor skills, the two components are no longer viewed as needed in automatized, expert handwriting. We tested this assumption by assessing the contributions of these components to handwriting performance in a group of 33 adult participants. Linear regressions were used to examine whether dexterity, manual praxis, working memory, inhibition and flexibility predict handwriting speed, legibility, and fluency. Results revealed that fine motor skills were a significant contributor to all aspects of handwriting performance. Executive functions also predicted handwriting performance, with a significant effect of flexibility on writing speed and of working memory on legibility. These findings highlight that, even at a high level of expertise and automatization, handwriting remains a skill whose performance depends on executive and fine motor control capacities. They support a predictive coding account of graphomotor control, whereby internal forward and inverse models would support the execution and monitoring of handwriting movements. Our study raises important questions about the extent to which disorders in motor and executive processes can affect handwriting performance and highlights the need for further research into this complex motor behavior
Un groupe de lycéens en LV3 coréen sur Facebook : illustration d'une agentivité collective au service de l’apprentissage ?
No full textInternational audienceAgency, as defined by Bandura (2006), is primarily referenced in studies on distance learning in higher education and/or adult education, and it appears much less frequently in those focusing on secondary education. This is partly due to the fact that questions of student engagement, as well as the motivation to learn, inevitably come into conflict with the traditional structure of schooling. Consequently, the issue of student agency seems conceivable only outside the formal school framework. With this assumption in mind, we undertook an analysis of interactions among members of a Facebook group created in 2012 by high school students learning Korean. The findings reveal the strong and sustained participation of students, particularly in Korean, along with exchanges that highlight key elements of self-directed learning. They also show that agency, both individual and collective, manifests in interactional situations tied to the formal aspects of schooling. The space that students freely created and chose outside of their high school Korean classes appears to reveal a framework—or at least a relational dimension (teacher-student)—typical of the school environment, which, while role-played, contributes to student engagement in learning the target language.Le concept d’agentivité, tel que défini par Bandura (2006), est essentiellement repris dans les études relatives aux formations à distance dans l'enseignement supérieur et/ou dans la formation des adultes, il l’est beaucoup moins dans celles portant sur l’enseignement dans le secondaire. Cela tient pour une part au fait que les questions de l’engagement comme celle de la motivation des élèves à entrer dans l’apprentissage se heurtent nécessairement à celle de la forme scolaire. La question de l’agentivité des élèves semble alors ne pouvoir s’envisager qu’en dehors du cadre formel de l’école. C’est à partir de ce postulat que nous avons entrepris l’analyse des échanges entre les membres d’un groupe Facebook créé par des lycéens apprenants de coréen en 2012. Les résultats permettent de mettre au jour la forte participation des élèves notamment en coréen, et sa continuité, ainsi que des échanges qui renvoient à des éléments clés de l’apprentissage auto-dirigé. Ils montrent également que l’agentivité, à la fois individuelle et collective, se manifeste aussi dans des situations d’interactions correspondant à ce qui relève de la forme scolaire. L’espace créé et choisi librement par les élèves, en marge de leurs cours de coréen suivis au lycée, semble ainsi révéler un cadre ou pour le moins une dimension relationnelle (enseignant-enseigné) propre à la forme scolaire, laquelle tout étant jouée participe de l’engagement des élèves dans l’apprentissage de la langue cible
COVID-19 vaccine hesitancy and perceived post-vaccination adverse event: Findings from a cross-sectional survey
No full textInternational audienceIntroduction: In Quebec, COVID-19 vaccine uptake among adults was high for the first two doses but decreased for the subsequent booster doses. This study assesses the relationships between attitudes towards vaccination and self-reported experience and severity of adverse events following immunization (AEFIs).Methods: A web survey of Quebec adults who received at least one dose of the COVID-19 vaccine was conducted in September 2023. Participants share their level of vaccine hesitancy before vaccination and their experience with AEFIs after receiving a dose. Participants were asked to note the severity of the symptoms they believed were due to vaccination. Intention to receive other vaccines in the future was questioned. Two coders performed a qualitative content analysis on reported AEFIs (N = 3808). Descriptive and multivariate logistic regression analyses were performed.Results: Among the 8419 vaccinated respondents, 46.7 % reported having experienced AEFIs. Fatigue or malaise (20.7 %), injection site disorder (17.3 %), musculoskeletal pain (11.2 %), headache (11.0 %), and fever (10.6 %) were the most commonly reported, respectively. Respondents who were very hesitant before the COVID-19 vaccine reported more frequently having a severe AEFI compared to those who were not hesitant (25.0 % vs 3.4 % =, p < 0.001). This affirmation stays true when all severity of adverse events are considered (68.7 % vs 36.9 %) (p < 0.001). Younger age (aOR = 0.98), being a female (aOR = 1.31), a higher education level (University degree aOR = 1.56 vs high school or less), being vaccine-hesitant in general (aOR = 1.69 vs non or less hesitant) were significantly associated (p < 0.001) with self-reported AEFIs in multivariate analysis. Self-reported AEFIs that prevented doing activities (aOR = 4.87) and being vaccine-hesitant in general (aOR = 4.94) were significantly associated with reduced intention to receive other vaccines in the future.Conclusion: Vaccine hesitancy could influence self-reported AEFIs and their perceived severity. Transparent and tailored communication explaining AEFIs while emphasizing strategies to mitigate these effects could helpful. Our findings also have implications for pharmacovigilance

Métiers de l'Avenir en Sciences Humaines : Innovation et Pédagogie face à l'Intelligence Artificielle: Rapport : Cartographie des métiers et formations - Diagnostic et prospective
No full textCe rapport présente la première phase d’un projet prospectif initié par la Faculté des langues de l’Université de Strasbourg, visant à anticiper l’impact de l’intelligence artificielle sur l’insertion professionnelle de ses diplômés et à adapter ses formations en conséquence.L’objectif est d’établir une cartographie exhaustive des métiers exercés par les diplômés de licence et de master (2015-2024), d’identifier les secteurs d’emploi et d’évaluer l’impact potentiel des technologies d’IA sur les compétences requises.L’étude repose sur trois sources de données complémentaires : les enquêtes d’insertion professionnelle de l’ORESIPE, l’annuaire du Réseau Alumni et un questionnaire diffusé auprès des anciens diplômés portant sur leurs usages et perceptions de l’IA.L’analyse révèle une insertion professionnelle globalement réussie ainsi qu’une diversification marquée des débouchés. Les métiers traditionnels ne représentent plus que 22 % des parcours, tandis que de nouveaux secteurs émergent : gestion de projet , communication et marketing, numérique et informatique. Le questionnaire confirme l’adoption croissante de l’IA et met en évidence un besoin urgent de formation à ces technologies, accompagné d’une forte demande de développement de l’esprit critique face aux outils numériques.Cette cartographie met en lumière la résilience des diplômés face aux transformations technologiques et fournit les fondations des prochaines phases du projet : expérimentation de scénarios pédagogiques intégrant l’IA et évaluation de leur impact sur l’employabilité. Elle souligne l’importance d’articuler compétences linguistiques, savoir-faire transversaux et maîtrise critique des technologies émergentes pour préparer les futurs diplômés à des métiers en constante évolution
